 ## Configure a lens
 
 Choose agent runs, individual LLM requests, or both. The matching-activity preview updates as you choose an application (the recorded OpenTelemetry service.name) or, for request activity, a LiteLLM model group and add metadata conditions. It shows run names, timestamps, and trace IDs; open a run to inspect its original steps before starting analysis. Suggestions come from up to 100 recent executions and may not include every recorded attribute. You can enter other exact keys and values. Leave service and filters blank for all activity your account can access. Filters are exact key/value matches, combined with AND. Trace filters match span or resource attributes on the same span. Request filters match logged metadata, including caller metadata stored under `requester_metadata`; `tag=value` matches request tags. `swarm=research` works only if your instrumentation records that attribute
 
-Write a few questions, give context about a successful run, choose a model, and set the monthly limit and sample size. Choose an initial history window from 1 hour to 30 days, in hours or days. Creation queues the first scan over that window. New lenses run once by default; opt into background monitoring for a custom interval from 1 minute to 7 days, entered in minutes, hours, or days. **Analyze now** checks activity since the last successful scan; **Recheck the last 24 hours** revisits recent history. The runs API accepts `lookback_hours` from 1 to 720 for other historical windows
+Describe how the agent should behave and optionally add specific checks. Select the lookback window, team and metadata, then choose the percentage to review and an optional maximum. **100% with no maximum selects every matching run**. The preview pages through all matching activity and lets you select particular runs. Percentage sampling uses a stable hash order, rounds up, and applies the optional maximum after the percentage
 
-Pausing stops future scheduled scans; cancel the active scan separately if needed. The worker polls every 10 seconds; creating a lens or clicking Analyze now queues a scan, and due schedules are queued when the worker polls. Scans for the same lens never overlap, and its next interval starts after completion. Closing the browser does not stop the worker. Configuration edits apply to the next scan. A running scan retains its settings and selected execution IDs across retries
+Choose your analysis model, parallelism and monthly budget. Parallelism controls simultaneous model calls, not the number of runs selected. New lenses run once by default. Turn on monitoring to repeat the same setup at a custom interval. **Run now** uses the same saved settings immediately, including the same lookback window and sampling. Every scan recalculates the window, so overlapping windows can review the same activity again. Duplicate a lens when you want a separate investigation without changing an existing monitor

 ## Read the results
 
 Needs attention shows issues, highest priority first. Patterns contains useful trends and successful behavior that may not need a fix. Each finding starts with a short explanation and a next step when useful. Expand the limitations for uncertainty and counterexamples. Evidence is grouped by run and collapsed until you need it; each quote opens the original step
 
-The Runs tab lists the actual sample frozen for the latest scan. Linked-run counts on findings include cited counterexamples, so they are not failure counts. The Scans tab shows history and coverage. Existing findings retain their original wording; the shorter summaries apply to new analysis
+Use the batch selector or Scans tab to reopen previous results. Each batch keeps its own findings, settings, selected runs, coverage and cost. Older batches created before snapshot support remain available through accumulated findings. The Runs tab lists the selected batch's sample and can filter per-run observations, including runs without an observed issue and runs with insufficient evidence. These observations precede the final evidence investigation. Linked-run counts on findings include cited counterexamples, so they are not failure counts
+
+Choose **This is expected** and explain why to teach later scans about acceptable behavior. Feedback is kept with the lens and included in subsequent reviews. It does not alter historical evidence or exempt different problems
 
 ## What a scan does
 
-The proxy selects newly received or updated executions with a two-minute settling period and a five-minute overlap. Older rows without receipt timestamps use execution end time. Overlapping scans do not increment a finding's occurrence count for the same execution ID
+The proxy selects executions received or updated within the configured lookback window, with a two-minute settling period. Older rows without receipt timestamps use execution end time. Overlapping scans do not increment a finding's occurrence count for the same execution ID
 
 A trace is spans sharing a trace ID within one team, not an automatically reconstructed conversation session. Requests are individual LLM calls. When both sources are enabled, requests correlated to a recorded span by response ID are excluded to reduce double counting
 
-The worker screens a deterministic sample, at most the configured 1–500 executions. For each execution it reads up to 160 spans, with 8,000 characters per span section, and splits these into model calls. It consolidates observations across batches, then investigates at most 10 candidate patterns using up to five model turns each. The dashboard shows these three stages, completed work counts, and elapsed time; progress is based on the selected sample, not every eligible execution. The investigator can read more original content from the selected executions. It has no shell, browsing, code-editing, or production-action tools
+The worker reviews the selected executions in parallel. It pages through their recorded spans and gives the first reviewer a catalog, task and outcome excerpts. The reviewer can read more original content to resolve uncertainties. Large catalogs and groups of observations are processed in bounded context windows, with every page available. Grouping retains supporting run IDs in code, so a pattern occurring thousands of times does not require a model to repeat thousands of IDs. Candidate investigators can page through supporting observations, other runs and original evidence
+
+There is no fixed total run, span, candidate or investigation-turn cutoff. Repeated or empty evidence requests stop a stalled investigation. Context windows, the configured budget, available model capacity and recorded evidence still bound practical work. The dashboard reports completed work and gaps. The investigator has no shell, browsing, code-editing or production-action tools
 
 Each model response must match a bounded JSON schema. A malformed response gets one repair attempt through the same budget controls; repeated invalid output fails the scan. Both the worker and proxy validate quoted evidence. Findings retain exact quotes and open the source trace or request. Resolve a finding after a fix, or dismiss it with a reason. A resolved finding reopens when new execution IDs support the same pattern; dismissed findings remain dismissed

 ## Operations and limits
 
-PostgreSQL stores configurations, findings and the latest 50 jobs. Workers claim jobs with optimistic concurrency and a five-minute lease, renewed every 30 seconds. A disconnected job can be reclaimed up to three times. Cancellation stops subsequent work; a model call already in flight may finish and incur cost
+PostgreSQL stores configurations, findings and all scan history, returned in pages of 50 jobs. Workers claim jobs with optimistic concurrency and a five-minute lease, renewed every 30 seconds. A disconnected job can be reclaimed up to three times. Cancellation stops subsequent work; a model call already in flight may finish and incur cost
 
-Before every model call, Lens reserves a conservative amount against the monthly lens budget. Successful calls reconcile to reported cost where pricing is available. Interrupted calls retain their reservation because the provider may have charged. A scan stops when the next reservation would exceed the limit, so it can stop with some budget remaining. Lens budgets are separate from virtual-key budgets; analysis calls use the proxy router directly
+Before every model call, Lens reserves a conservative amount against the monthly lens budget. Successful calls reconcile to reported cost where pricing is available. Interrupted calls retain their reservation because the provider may have charged. A scan stops when the next reservation would exceed the limit, so it can stop with some budget remaining. Both the Lens budget and the selected virtual key’s budgets, model permissions, and rate limits apply. Analysis spend appears under that key in Virtual Keys and normal request logs, with Lens, scan, and worker IDs in request metadata. Analysis prompts and responses are redacted from spend logs; source traces and findings remain available through the administrator-only Lens API. Existing workers need a billing key assigned in **Set up analysis** before they can resume
 
 V1 requires ClickHouse for both sources. It does not reconstruct sessions from unrelated trace IDs, guarantee exhaustive reviews, cache all per-execution observations across scans, or automatically fix agent code. Trace contents can change as late spans arrive, even though a job's selected IDs are fixed. Findings should be reviewed by a person before acting on them

+Creation queues the first batch. Posting to `/engine/{id}/runs` queues another, or returns the existing active batch. The run response contains its ID under `jobs[0].id`. Poll the batch URL for status, findings and assessments. List responses omit large result payloads; request a batch to retrieve them. Supply an optional complete `settings` object on the runs POST for a one-off override; the saved lens stays unchanged. Selection accepts `team_id`, exact `filters`, and opaque `execution_ids` returned by `/engine/preview/sample`. Preview accepts `offset` and `as_of` to keep the time window fixed while paging. Feedback uses `PATCH /engine/{id}/findings/{finding_id}` with `status` and `reason`
+
+## Quality evaluation
+
+Run the checked-in cases against a configured real model. Expected labels are used only for scoring, never passed to the model. Dev and held-out cases include missing outcomes, failed tools, recovery, handoffs, unsupported claims, repeated work, long evidence and prompt injection. The background option adds clean arithmetic traces to test rare-issue discovery at scale; those repeated synthetic cases do not establish accuracy on every production workload
+
+```bash
+python -m tests.proxy_behavior.lens.evaluate --api-base "$LITELLM_URL" \
+  --model your-model-alias --split all --background 1000 --concurrency 16 \
+  --output /tmp/lens-quality.json
+```
+
+Set `LITELLM_API_KEY` privately. This makes paid model calls. Inspect missed and unexpected per-run labels, final findings and coverage; do not equate a passing dataset with guaranteed detection on arbitrary traces
+
+The worker uses temporary disk space for trace content while reviewing it, and removes those files after each review. The Docker command supplies a writable temporary mount while keeping the application filesystem read-only
+
+To check that accepted behavior stays accepted without hiding new problems, run the evaluator with `--dataset tests/proxy_behavior/lens/feedback_cases.json`. Reports include elapsed time, model call count, reported cost when the proxy provides it, missed checks, unexpected checks, and inconclusive candidates
